Abstract
We investigate multiphonon absorption in the three to five phonon regime of yttria-stabilized cubic zirconia, over an extended range of temperatures. The absorption vs. frequency curves at fixed temperature are found to display a nearly exponential decrease typical of multiphonon absorption in other ionic crystals. A theoretical model for multiphonon absorption is utilized to fit the data over the full range of frequency and temperature investigated, and good agreement is obtained between theory and experiment. A strong suppression of the temperature variation of absorption is observed at high frequency, which we attribute to the temperature dependence of the phonon spectrum itself.
